\ vide means or regulating the amount of air admitted to the manifold and to lace the air pipe adjacent the exhaust manifold so that the air will be heated by the products of combustion.

Still another object of the invention is to provide an improved mixing device for dellvering the air and gasolene' into the manifold.

The invention also consists in certain other `features of construction and in the combination and arrangement of the several parts. to be hereinafter fully described, illustrated Yin the accompanying drawings and specifi` cally inted out in the appended claim.

In dscribing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a diagrammatic view showll`one application of my invention;

'g. 2 is a like view showing another application of my invention;

In these views 1 indicates the inlet manifold of an internal combustion motor and 2 indicatesthe carbureter connected with the lower end' thereof. 3 is the exhaust manifold while 5 indicates the gasolene vacuum tank. In ca ing out my invention I bore a hole in t e mlet manifold to receive the mixing device 6 which has that portion which lies within the manifold, of

tubular shape and provided with the rfol rations 7 The projecting portion o said device receives one end of the gasolene supplyhpipe 8 and said portion is provided wit pipe 1Q, the ends of said pipes or tubes belng sultably connected withsaid device to prevent leaka e. The air pipe 10 is bent to contact with t e exhaust manifold 3 so that said pipe will be heated by the products or combustion and said pipe passes through the dash 11 and has its u per end connected with a screw threaded) bushing 12 carried by the dash. This bushing is provided with the slots 13 for admittin air to the interior of the bushing and t e tube and these slots are controlled by a cap 14 which engages said bushing. This cap is provided with a hand-hold 15 so that the same can be manipulated to close more or less the slots. The gasolene pipe 8 is connected with a tubular member 16 which has its lower end connected with the vacuum tank 5 and its upper end passing through the dash 11. This upper end is screw-threaded and receives a cap 17. VThis cap carries a valve rod 18 extending through the tubular member and provided at its lower end with a valve 19. This valve is adapted to engage with a valve seat 20 formed in the tubular member between the connection of the pipe 8 and its lower end. Thus by manipulating 86 Y the cap 17 the valve 19 may be adjusted relative to the seat 2O so as to control the asolene flowing from the tank 5 into the tu 8.

It will thus be seen that the en e may be primed with a mixture of gaso ene and air which will be thoroughly mixed by the mixing device as it isintroduced into the manifold. Both the supply of gasolene and air are controllable from the dash.

Fi 2 shows the device applied to an automoile in which the gasolene ltank 21 is located under the front seat and a vacuum Vtank is not used. In vthis form the maln gasolene line 22 is provided with a T 23 and the tubular member 16 has' its lower e pipe or tube 8 leads from the tubular member to the end of the mixingdevice as before described. In this case the cap 17 of the tubular member would pro'ect through the door of the automobile. his form of infv a projection 9 for receiving the air vention operates similarly to that just described.

I make that portion of the tube 10 which rests on the exhaust manifold exible, as at 10' So that in het weatherthis part of the device may-be `lifted o5 the manifold.

M'y device acts to reduce the amount of gasolene used as the explosive mixturey may be made leaner by reason of the fact that the airis heated before itis introduced in the manifold. Any amount of air may be introduced b manipulating the cap.

It is thong t from the foregoingdescriptionA that the advantages and novel features of mdzsinvention will be readily apparent. I ire it to be understood that I may make changes in the construction and in the .eombinatm` and arrangement of the several naam parts, provided that such chales fall withaim. Y 20 .trolling said pipe, means for controllin the valve from a point adjacent the driver s seat, an air pipe connecting` with said mixingvdevice and having its upper end carried 80 by the dash, a slotted bushin connected with said and carried by t e dash'and a cap 'en ging said bushing for controlling the supp y of air to the '1pe. f
